Classify the predicted biomass from the biogeochemistry module into different vegetation
classes.

The biogeochemistry module simulates monthly carbon and nutrient dynamics for a given ecosystem.
Above- and below-ground processes are modeled in detail, and include plant production, soil organic
matter decomposition, and water and nutrient cycling. Parameterization of this module is based on
the lifeform composition of the ecosystems, which is updated annually by the biogeography module.
